Panels are made from 14 gauge steel with G235 (Z720) galvanized coating. Both straight and curved wall panels have 7 strategically located holes at both ends ensuring positive and accurate alignments. The ends of each panel are made with a recessed end making for a seamless panel connection. The overlap end of each panel is fastened with our Press-Lock® fastening system. Wall braces are secured in place using our Press-Lock® system which reinforces and stabilizes each panel.
